Customs Clearance of Calcium and Magnesium in Iran (HS Code + Documents & Permits)

Calcium and magnesium are two vital elements across various industries, playing key roles in industrial, pharmaceutical, and food productions. Calcium is commonly used as Calcium Carbonate (CaCO₃) and Calcium Hydroxide (Ca(OH)₂). These compounds hold a special place in construction, chemical, and pharmaceutical industries. Magnesium is also used in several forms including Magnesium Oxide (MgO) and Magnesium Sulfate (MgSO₄). Owing to their unique chemical and physical properties, these two elements are used in a wide range of products such as lightweight alloys, refractory materials, and nutritional supplements.

1) Overview & Industrial Uses of Calcium and Magnesium

Industrial & Commercial Uses of Calcium — Construction: Calcium is a main ingredient in the production of cement and lime. Portland cement—one of the most widely used types—contains significant amounts of calcium carbonate.
Chemical Industries: Calcium is used in manufacturing various plastics, paints, and detergents. Calcium carbonate acts as a key filler in these industries.
Food & Pharma: Calcium carbonate and its derivatives are used as dietary supplements to supply calcium and in various drug formulations.

Magnesium Applications — Metals: Magnesium is a primary component in producing light, high-strength alloys used in automotive and aerospace industries.
Chemical Industries: Magnesium oxide is a refractory material used in building industrial furnaces and in manufacturing pyrotechnic chemicals.
Pharma & Food: Magnesium sulfate and other magnesium compounds are used in supplements and medicines related to muscle function and bone health.

2) Key Points for Clearing Calcium & Magnesium from Customs

Clearing calcium and magnesium—considered strategic chemical/mineral materials—requires strict compliance with customs laws, regulations, and procedures. Below are the critical technical details relevant to clearing these materials from Iranian customs.

3) Customs Tariffs & HS Codes

Calcium Carbonate (CaCO₃): A highly used mineral compound classified under HS code 28365000. This covers all forms and grades, including PCC (precipitated) and GCC (ground).

Magnesium Oxide (MgO): Widely used in refractory, pharma, and chemical industries; recognized in Iran under HS code 25199020. This includes calcined and non-calcined forms.

Other derivatives and compounds: Additional calcium and magnesium derivatives—including calcium hydroxide, calcium chloride, magnesium sulfate, and magnesium carbonate—each have their own HS code. Depending on grade, purity, and end-use, the applicable tariff can vary and must be selected carefully.

Item	Short Description	HS Code
Calcium Carbonate (CaCO₃)	PCC/GCC; industrial, food & pharma filler	28365000
Magnesium Oxide (MgO)	Furnace refractory, chemical/pharma uses	25199020

Final HS selection for calcium hydroxide, calcium chloride, magnesium sulfate, and magnesium carbonate depends on grade, purity, form, and end-use.

4) Required Documents & Records

Essential Documentation — Certificate of Origin (CO): This crucial document indicates the manufacturing origin of imported calcium or magnesium and is a legal requirement for clearance. It must be issued by the Chamber of Commerce in the origin country and affirmed by competent Iranian authorities. It may also affect preferential tariffs or exemptions.

Commercial Invoice: Must include all required details such as unit price, exact quantity, payment terms, and other sales conditions. It should be clear, unambiguous, and signed by both seller and importer.

Technical Specs & Packaging: Provide detailed technical data including purity level, particle size distribution (PSD), crystalline structure, and other chemical/physical properties. Also include complete packaging information (materials used and standards followed). This is needed for compliance with national and international standards.

Quality Testing & Standards Compliance: For calcium and magnesium imports, quality tests and compliance checks by accredited domestic labs are required. Tests may include purity, thermal resistance, and specific chemical reactions.

Chemical Regulations: Due to the chemical nature of these materials, clearance is overseen by the Environmental Organization, the National Standards Organization, and the Ministry of Health. Safety, transport, and storage requirements must be met throughout the process.

Customs Preferences & Exemptions: Review any customs exemptions and preferential tariffs that may apply under international or domestic trade agreements to reduce import costs.

5) Import Conditions

Sources of Supply: Iran mainly imports calcium and magnesium from China, Turkey, and the UAE—major global producers.
Environmental & Health Standards: Compliance with environmental and health standards is crucial. Quality approval and absence of contaminants are key requirements for clearance.

6) Order Registration & Required Permits

Importers must register their orders in the National Trade System before goods enter the country and obtain necessary permits from relevant agencies. This helps reduce issues and delays at customs.

7) Special Conditions for Import/Export of Calcium & Magnesium

Exporters: China, Turkey, and India are among the largest exporters of these materials.

Major Importers: Iran, the United States, and Germany are among the biggest importers worldwide due to significant industrial demand.

8) Market Status, Imports & Exports

Import/Export volumes to Iran: Iran is one of the largest importers of calcium carbonate and magnesium oxide in the region. High demand from construction, chemical, and pharma sectors keeps import volumes substantial.
Exports: While Iran is not a major exporter in this field, certain calcium- and magnesium-based products are exported to neighboring countries.
